The Titan Boulder Stone Sets from the WIO brand consist of a combination of different rounded stones in a grained grey. Their unique metamorphic stone has the same grey-blue-green colour palette and filigree white layers as the Titan Stone. The difference lies in its beautifully rounded surface, which mimics the shape of timeless boulders sculpted by the forces of nature. Boulders have the natural shape of a stone polished by erosion and weathering.

Titanium Boulder, created by intense pressure and high temperatures deep inside the earth, adds a stunning touch to any Iwagumi-style aquascape. Its curved surface reflects light in different ways, highlighting different colours and creating an appealing, ever-changing visual spectacle.
Titan Boulder is an inert rock that does not affect water parameters and is therefore safe for all aquatic life, including sensitive plants and animals.

A set always consists of different sized stones and small pieces of stone to create a charming landscape with depth effect. This rock has no influence on the water parameters.


  • Unique grey-blue-green stone with white layers and rounded surface
  • Ideal for aquascapes in Iwagumi style
  • Light-reflecting properties that highlight different colours
  • Does not affect the water parameters
  • Safe for sensitive aquatic plants and creatures


These Rocks sets are untreated natural products. They can be used in aquariums as well as in terrariums. It is recommended to clean and rinse Rocks decoration under running water before using it in the aquarium. This removes the finest stagnant particles, which can otherwise cause cloudiness when a new aquarium is set up. Slight residues of moss or lichen cannot be ruled out completely.
